The purpose of this study was to evaluate the interaction effects winter cover crops (hairy vetch, subclover and black oat) a bare soil, crop biomass management (incorporated into soil or left on surface as death mulch), nitrogen (N) fertilization level (0, 75 150 kg ha−1 N) fruit yield quality parameters processing tomato. Hairy vetch residues increased (+57%), color index (+8%) sugar/acidity ...

this experiment was carried out to evaluations the allopathic foliar application of safflower)carthamus tintorius) aqueous extracts on growth and leaf cell membrane leakage of hairy vetech (vicia villosa).  the experimental arrangement was crd in four replications. results showed that by increasing the concentration of safflower extracts, shoot dry weight and peroxidase enzyme activity decrease...

This study aimed to elucidate the chemical response of hairy vetch (Vicia villosa Roth) interspecific competition by rye (Secale cereale L.). Hairy plants were grown as target in a mixture with different densities (0, 1, 2, and 4). Twelve flavonoids shoot, root, root exudate quantified high-performance liquid chromatography-tandem mass spectrometry (HPLC-MS/MS). Kaempferol 3-O-{β-D-rhamnosyl-(1...

For improvement of these traits in hairy vetch, it is imperative to gain insight into the magnitude of variabilFor improvement of hairy vetch (Vicia villosa Roth) as a winter ity present in the species, as this will provide the basis cover crop, it is necessary to gain insight into the magnitude of variabilfor effective selection. Phenotypic variability is the obity present in the species. This...

Field experiments at Oakes, ND, USA in 2010 and Carrington, ND, USA in 2011 were conducted to evaluate the potential for cover crops grown in the Northern Great Plains, USA in order to reduce weed emergence and density in irrigated potatoes. Treatments included five cover crop treatments and three cover crop termination treatments. Termination of cover crops was done with glyphosate, disk-till,...

Producers are interested in tactics for managing crop residues when growing corn after spring wheat. We compared five systems of managing spring wheat residues: conventional tillage, no-till, strip-till, cover crop (hairy vetch) with no-till, and cover crop with strip-till following spring wheat. Conventional tillage consisted of chisel plowing and disking, whereas strip-till consisted of tilli...

Compatible rhizobia strains are essential for nodulation and biological nitrogen fixation (BNF) of hairy vetch (Vicia villosa Roth, HV). We evaluated how past HV cultivation affected nodulation and BNF across host genotypes. Five groups of similar HV genotypes were inoculated with soil dilutions from six paired fields, three with 10-year HV cultivation history (HV+) and three with no history (H...

Experiments were conducted to determine the ability of citrate to enhance the plant uptake of weathered 2,2-bis(p-chlorophenyl)1,1-dichloroethylene (p,p'-DDE) from soil. Plots containing three rows of clover, mustard, hairy vetch, or rye grass were constructed in soils containing p,p'-DDE. On 11 occasions, the rows of each crop received water or sodium citrate (0.005 or 0.05 M). For each crop, ...
